Building over or near a sewer

If you’re planning to improve your home by extending it, adding a conservatory, annex or garage it’s likely there will be pipes within your land. As well as checking the local authority's Building Regulations, it's important you work with us to make sure the pipework is protected and our access isn't restricted.
